You could route it above the pavements with

Highly popular with first-floor residents, I should imagine.
It would ruin the streetscape if it were above street level.
The clearance required is also much greater. Subways beneath the roads
would
be shallow and could easily come back up to street level.
You've never been to a town with arcades at first floor level then? Or one
with an overhead tramway/railway system?
Do they regularly try to fit these overhead constructs into existing
narrow streets that are hundreds of years old?
